Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a capping assembly and a washing machine. Background Technology

[0002] As people's living standards continue to improve, washing machines have gradually become one of the essential home appliances in families. While automatically washing clothes, they also reduce the labor intensity of consumers and improve their quality of life.

[0003] Based on the rotation method, washing machines are divided into front-loading washing machines and top-loading washing machines. Top-loading washing machines have a pulsator at the bottom of the washing tub. During the washing process, the rotation of the pulsator drives the water flow to rotate, thereby achieving the tumbling and washing of the clothes.

[0004] Existing top-loading washing machines, because the pulsator is located at the bottom of the washing tub, will cause easily floating clothes, such as down jackets or light silk garments, to float on the water surface. Furthermore, when the amount of laundry is small, the internal space of the washing machine is relatively large, which reduces the friction between the clothes and further reduces the washing effect. Summary of the Invention

[0005] One object of the present invention is to provide a capping assembly to enhance the washing effect of a washing machine.

[0006] Another objective of this invention is to provide a pulsator washing machine that improves the washing effect of pulsator washing machines and is more suitable for washing light clothes and small amounts of clothes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pressure cap assembly is used in a pulsator washing machine. The pressure cap assembly includes a pressure cap and a pressure post detachably connected to one side of the pressure cap. The projection of the pressure post on the pressure cap is located inside the pressure cap. The outer wall surface of the pressure post is provided with lifting ribs, and multiple lifting ribs are arranged at intervals along the circumference of the pressure post.

[0009] As a preferred technical solution for the pressure cap assembly, the pressure cap and the pressure column are detachably connected. By detachably connecting the pressure column and the pressure cap, when the amount of laundry is large, the pressure column can be removed from the pressure cap, and only the pressure cap is used to press the laundry down, avoiding the pressure column reducing the washing space. When the amount of laundry is small, installing the pressure column on the pressure cap increases the pressing depth of the laundry and reduces the space between the pressure cap and the bottom of the washing tub, thus facilitating the washing of small amounts of laundry.

[0010] As a preferred embodiment of a pressure cap assembly, the pressure cap includes a pressure cap plate and elastic arms vertically connected to the pressure cap plate. At least two elastic arms are spaced apart around the pressure post, and each elastic arm has a hook portion extending from its end toward the pressure post. A groove is formed on the outer peripheral wall of the pressure post, and the inner side of the elastic arm abuts against the outer surface of the pressure post, with the hook portion engaged in the groove. By providing elastic arms, during installation, the hook portion can be disengaged or engaged in the groove by bending the elastic arm to deform it, simplifying the installation process.

[0011] As a preferred technical solution for a pressure cap assembly, the elastic arm extends with a pressing portion in a direction away from the pressure post. By providing the pressing portion, the elastic arm can be deformed by pressing the pressing portion, thereby realizing the disengagement or engagement of the hook portion with the slot, improving the convenience of disassembly and assembly operations.

[0012] As a preferred technical solution for the pressure cap assembly, a limiting plate is provided between two adjacent elastic arms. One end of the limiting plate is connected to the pressure cap plate, and the inner wall surface of the limiting plate is in contact with the outer wall surface of the pressure column. By providing the limiting plate, the contact area between the pressure column and the pressure cap can be increased, thereby increasing the friction between the two and preventing the pressure column from detaching from the pressure cap.

[0013] As a preferred embodiment of the pressure cap assembly, the pressure cap includes a pressure cap plate, and the pressure post is detachably connected to a first side of the pressure cap plate. A scrubbing structure protrudes from the first side of the pressure cap plate and / or the side of the pressure post away from the pressure cap plate. The scrubbing structure enhances the scrubbing effect on the clothes, thereby improving the washing effect.

[0014] As a preferred technical solution for the capping assembly, the length of the pressure column perpendicular to the capping direction is adjustable. This allows for adjustment of the overall length of the pressure column to suit different loads of laundry. Specifically, when washing a relatively large load, the overall length of the pressure column can be shortened to increase the space between the capping plate and the bottom of the washing tub; conversely, when washing a relatively small load, the overall length of the pressure column can be lengthened to reduce the space between the capping plate and the bottom of the washing tub, thus increasing the pressure on the clothes.

[0015] A pulsator washing machine includes a washing tub and a pressure cap assembly as described above. The pressure cap assembly is detachably connected to the interior of the washing tub, and the pressure post is located between the pressure cap and the bottom of the washing tub. A washing space is formed between the pressure post, the bottom of the washing tub, and the tub wall.

[0016] As a preferred technical solution for a pulsator washing machine, the installation position of the pressure cap inside the washing tub is adjustable in the axial direction of the tub. Therefore, the installation height of the pressure cap assembly can be adjusted according to the material and quantity of laundry, meeting different washing needs and offering high flexibility in use.

[0017] As a preferred technical solution for a pulsator washing machine, the pressure cover is slidably connected to the inner wall of the washing tub, so that the pressure cover assembly can float up and down under the influence of the washing water and / or the washing clothes. This arrangement can further improve the washing effect by patting the clothes through the reciprocating sliding of the pressure cover plate, and also allows the pressure cover assembly to automatically change the pressing depth of the clothes according to the amount of clothes.

[0018] The beneficial effects of this invention are as follows:

[0019] The pressure cap assembly provided by this invention can press clothes into the water during the washing process, preventing down or other lightweight clothing from floating on the surface and reducing the washing effect, thus ensuring that the clothes to be washed are effectively soaked in the water. Furthermore, by setting pressure columns, the pressing depth of the pressure cap assembly into the clothes can be increased, reducing the space between the pressure cap and the bottom of the washing tub. This reduces the space for clothes to tumble when washing a small amount of clothing in a pulsator washing machine, increasing friction between the clothes and the probability of friction between the clothes and the washing tub and pressure columns, thereby improving the washing effect. Simultaneously, the lifting ribs on the outer wall of the pressure columns can rub the clothes, enhancing the washing effect. The lifting ribs also cause the clothes to tumble, further improving the washing effect.

[0020] The pulsator washing machine provided by the present invention can improve the washing effect of clothes by setting the above-mentioned pressure cover assembly inside the washing tub, and is especially suitable for washing a small amount of clothes. Attached Figure Description

[0033] Example 1

[0034] like Figure 1 and 3 As shown, this embodiment provides a pulsator washing machine, which includes a body, a washing tub 2, a pulsator 3, and a drive device. The washing tub 2 is disposed inside the body and has a washing chamber for accommodating clothes. The pulsator 3 is rotatably disposed at the bottom of the washing tub 2. The drive device is installed inside the body and on the outside of the bottom of the washing tub 2 and is used to drive the pulsator 3 to rotate, thereby causing the clothes to tumble. The end of the washing tub 2 away from the pulsator 3 has an opening, which faces or faces the top of the body. A control panel and a top cover hinged to the control panel are installed at the top of the body. The control panel has a clothes inlet corresponding to the opening of the washing tub 2 for loading clothes. The top cover is hinged to the rear end of the control panel to open or close the clothes inlet.

[0035] The pulsator washing machine provided in this embodiment can be a fully automatic pulsator washing machine with integrated washer-spinner, that is, the washing tub 2 and the spin-drying tub are shared, and the washing tub 2 can rotate inside the machine body. Alternatively, it can be a pulsator washing machine with separate washer-spinner, that is, the washing tub 2 is fixed inside the machine body. In addition, the axis of the washing tub 2 in this embodiment can be fixed relative to the machine body, or it can be a pulsator washing machine that can be rotated and adjusted by an angle adjustment mechanism to change the tilt angle of the axis of the washing tub 2 relative to the vertical direction. Or, the pulsator washing machine provided in this embodiment can be a pulsator washing machine in which the pulsator 3 and the washing tub 2 can rotate in opposite directions. This embodiment does not specifically limit the specific type of pulsator washing machine. Existing pulsator washing machines that drive the washing of clothes through the pulsator 3 are all within the protection scope of this invention.

[0036] To improve the washing effect on clothes, in this embodiment, a pressure cap assembly 1 is detachably connected to the inside of the washing tub 2. The pressure cap assembly 1 includes a pressure cap 11 and a pressure column 12 connected to the lower surface of the pressure cap 11. The projection of the pressure column 12 on the pressure cap 11 is located inside the pressure cap 11, and a lifting rib 122 is protruding from the outer surface of the pressure column 12. Multiple lifting ribs 122 are arranged at intervals along the circumference of the pressure column 12.

[0037] The pulsator washing machine provided in this embodiment, by setting the pressure cap assembly 1, can press the clothes into the water during the washing process, preventing down or light-weight clothes from floating on the water surface and reducing the washing effect, and ensuring that the clothes to be washed are effectively soaked in the water. Furthermore, by setting the pressure column 12, the pressing depth of the pressure cap assembly 1 into the clothes can be increased, reducing the space between the pressure cap 11 and the bottom of the washing tub 2. This reduces the space for the clothes to tumble when washing a small amount of clothes in the pulsator washing machine, increasing the friction between the clothes and the washing tub 2 and the pressure column 12, thereby improving the washing effect. At the same time, the lifting ribs 122 set on the outer wall of the pressure column 12 can rub the clothes, thereby enhancing the washing effect. In addition, the setting of the lifting ribs 122 can also drive the clothes to tumble, further improving the washing effect.

[0038] In this embodiment, the pressure column 12 is preferably cylindrical to reduce sharp edges and better fit the shape of the washing tub 2. However, the present invention is not limited to this. The cross-section of the pressure column 12 can also be elliptical, rectangular with chamfers, or other shapes, as long as the setting of the pressure column 12 reduces the washing space between the pressure cover 11 and the bottom of the washing tub 2.

[0039] The outer diameter of the pressure column 12 is preferably greater than one-third and less than two-thirds of the inner diameter of the washing tub 2 to ensure a reasonable washing space and avoid insufficient washing space between the pressure cap 11 and the bottom of the tub, which would result in insufficient clothing capacity or difficulty in tumbling the clothes. Furthermore, the axial length of the pressure column 12 is preferably one-quarter of the axial length of the washing tub 2 and less than one-half the length of the washing tub 2 to ensure that the washing space on the side of the pressure column 12 can allow the clothes to be lifted and tumbled smoothly.

[0040] Preferably, the pressure column 12 and the pressure cover 11 are detachably connected. Therefore, when there is a large amount of laundry, the pressure column 12 can be removed from the pressure cover 11, and only the pressure cover 11 is used to press the clothes down, avoiding the pressure column 12 reducing the washing space. When there is a small amount of laundry, installing the pressure column 12 on the pressure cover 11 increases the pressing depth of the clothes and reduces the space between the pressure cover 11 and the bottom of the washing tub 2, thus facilitating the washing of small amounts of laundry. In other words, the detachable connection between the pressure column 12 and the pressure cover 11 allows for flexibility in washing different amounts of laundry.

[0041] To facilitate the assembly and disassembly of the pressure post 12 and the pressure cap 11, the pressure cap 11 and the pressure post 12 are preferably snap-fitted together. This design provides convenience for assembly and disassembly while avoiding the increased cost and easy loss of screws caused by screw connections.

[0042] like Figure 2-5As shown, preferably, the pressure cap 11 includes a pressure cap plate 111, and a pressure post 12 is disposed on one side of the pressure cap plate 111. An elastic locking arm 112 protrudes from the pressure cap plate 111. Multiple elastic locking arms 112 are axially spaced around the pressure post 1212. One end of each elastic locking arm 112 is connected to the pressure cap plate 11, and the other end is engaged with the outer wall of the pressure post 1212. By providing the elastic locking arm 112, during installation, the elastic locking arm 112 can be engaged or disengaged from the pressure post 12 by bending it to deform it. This simplifies the installation process and improves the ease of engagement and disassembly of the pressure cap 11 and the pressure post 12.

[0043] The elastic arm 112 includes an elastic arm 1121 vertically connected to the pressure plate 111, and a hook portion 1122 protrudes inward from the end of the elastic arm 1121 away from the pressure plate 111. A groove 121 is formed on the outer wall surface of the pressure post 12, the hook portion 1122 is engaged in the groove 121, and the inner side of the elastic arm 1121 abuts against the outer side of the pressure post 12.

[0044] Furthermore, the free end of the elastic arm 1121 extends with a pressing part 1123 in a direction away from the pressure column 12. When it is necessary to connect the pressure cap 11 and the pressure column 12, the operator operates the pressing part 1123 to bend and deform the elastic arm 1121 outward, increasing the space between the elastic arms 1121, so that the pressure column 12 can be inserted between the elastic arms 1121. Then, the pressing part 1123 is released, and the elastic arm 1121 returns to its original position under the action of elastic restoring force, so that the hook part 1122 is engaged in the slot 121. When it is necessary to remove the pressure column 12, the pressing part 1123 is pressed to bend the elastic arm 1121 outward, so that the hook part 1122 is disengaged from the slot 121, thereby realizing the separation of the pressure column 12 and the pressure cap 11.

[0045] In other embodiments, the pressure cap 11 and the pressure post 12 can also be installed using other existing snap-fit ​​structures, which will not be listed in this embodiment.

[0046] Furthermore, to improve the connection reliability between the pressure cap 11 and the pressure post 12, a limiting plate 113 is provided between two adjacent elastic arms 1121. One end of the limiting plate 113 is connected to the pressure cap 111, and the inner side of the limiting plate 113 is in contact with the outer side of the pressure post 12. By providing the limiting plate 113, the contact area between the pressure post 12 and the pressure cap 11 can be increased, thereby increasing the friction between the two and preventing the pressure post 12 from detaching from the pressure cap 11. More preferably, the end face of the pressure post 12 facing the pressure cap 111 abuts against the pressure cap 111.

[0047] To further facilitate the installation of the pressure post 12, the slot 121 has an annular structure, thereby reducing the installation and positioning requirements of the pressure post 12 and the pressure cap 11. In other embodiments, the slot 121 may also be individually provided for each hook portion 1122.

[0048] The lifting rib 122 is located on the side of the slot 121 away from the pressure plate 111 to avoid interfering with the connection between the pressure column 12 and the limiting plate 113. Preferably, the lifting rib 122 has a spiral structure, which can drive the clothes to tumble up and down along the spiral structure of the lifting rib 122, improve the tumbling effect, and thus enhance the washing effect on the clothes.

[0049] To further enhance the washing effect on clothes, a scrubbing structure is provided on the lower surface of the pressure plate 111 (i.e., the first side surface of the pressure plate 111) in the area not covered by the pressure post 12 and / or on the end face of the pressure post 12 away from the pressure plate 111. The scrubbing structure enhances the rubbing effect on the clothes, thereby improving the washing effect. The scrubbing structure can be a raised rib or a protrusion.

[0050] The pressure cap assembly 1 is preferably slidably disposed inside the washing tub 2, that is, the pressure cap 11 is slidably connected to the inner wall, so that the pressure cap assembly 1 can move up and down along the axis of the washing tub 2 under the action of the washing water flow or the washing clothes. This arrangement can beat the clothes by the reciprocating sliding of the pressure cap 111, further improving the washing effect of the clothes, and also allows the pressure cap assembly 1 to automatically change the pressing depth of the clothes according to the amount of clothes.

[0051] To prevent the capping assembly 1 from being too heavy and causing the clothing to be completely pressed down and unable to flip, the entire capping assembly 1 is made of lightweight materials such as rubber and silicone. Furthermore, the pressure post 12 can adopt a hollow structure to reduce the weight of the pressure post 12, thereby reducing the weight of the entire capping assembly 1.

[0052] To prevent the capping plate 111 from rotating relative to the washing tub 2, a sliding guide structure is preferably provided between the capping plate 111 and the washing tub 2. The sliding guide structure is used to guide the movement of the capping assembly 1 along the axis of the washing tub 2. Preferably, the sliding guide structure includes a guide rib 21 protruding from the inner wall of the washing tub 2 and a guide opening 1111 opened on the outer edge of the capping plate 111. The guide rib 21 passes through the guide opening 1111 and extends from the bottom to the top of the washing tub 2.

[0053] By setting guide ribs 21 inside the washing tub 2, the guide ribs 21 can not only guide the movement of the pressure plate 111, but also rub the clothes, thus further enhancing the washing effect. At the same time, the sliding guide structure can limit the movement direction of the pressure plate 111, and prevent the pressure plate 111 from rotating synchronously with the clothes, which would reduce the rubbing effect on the clothes.

[0054] In other embodiments, the outer edge of the cover plate 111 may be provided with a guide protrusion, and a guide groove may be provided on the inner wall of the washing tub 2, extending along the axial direction of the washing tub 2.

[0055] Preferably, multiple guide ribs 21 are arranged at intervals along the circumference of the washing tub 2 to improve the guiding effect and the rubbing effect on the clothes, and the guide openings 1111 are arranged one-to-one with the guide ribs 21.

[0056] To prevent the pressure plate 111 from popping upwards out of the washing tub 2, the pulsator washing machine is also equipped with an upper limit structure, which is used to limit the extreme position of the pressure plate 111 moving upwards along the axial direction of the washing tub 2.

[0057] In this embodiment, the pulsator washing machine is preferably a fully automatic washing machine that integrates washer and spin dryer. A balance ring 4 is disposed above the washing tub 2. The inner diameter of the balance ring 4 is smaller than the inner diameter of the washing tub 2, and the balance ring 4 forms the aforementioned upper limit structure. The balance ring 4 is an existing structure on fully automatic pulsator washing machines. Using the balance ring 4 as the upper limit structure simplifies the manufacturing of the pulsator washing machine. The balance ring 4 can be integrally formed with the washing tub 2, or it can be separately disposed and detachably connected.

[0058] In other embodiments, the upper limit structure may also be a protrusion protruding from the inner wall of the washing tub 2. Several protrusions may be arranged at intervals along the circumference of the washing tub 2, or the protrusions may be in the form of a ring structure.

[0059] Furthermore, the upper surface of the cover plate 111 is provided with several water passage holes (not shown). The water passage holes allow water to pass through the cover plate 111 during its up-and-down movement, thus preventing the cover plate 111 from sliding up and down due to water pressure.

[0060] Example 2

[0061] like Figure 6 As shown, this embodiment provides a pulsator washing machine, and the pulsator washing machine provided in this embodiment has a basically the same structure as the pulsator washing machine provided in embodiment one, except that the connection method between the pressure cap assembly 1 and the washing tub 2 is different. This embodiment will not describe the same structure as embodiment one.

[0062] In this embodiment, the installation position of the capping assembly 1 on the inner wall of the washing tub 2 is adjustable in the axial direction of the washing tub 2. Thus, the installation height of the capping assembly 1 can be adjusted according to the material and quantity of laundry, meeting different washing needs and providing high flexibility in use.

[0063] Preferably, at least two sets of mounting components are spaced apart along the height direction on the inner wall of the washing tub 2. Each mounting component includes at least two mounting pieces 5 spaced apart along the axial direction of the washing tub 2. Each mounting piece 5 has a slot 51 with an opening facing the inside of the washing tub 2, into which the side of the cover plate 111 is inserted. This type of mounting piece 5 has a simple structure, is easy to manufacture, and allows for adjustment of the height position of the cover assembly 1 by connecting it to mounting pieces 5 at different heights.

[0064] Mounting component 5 may include two mounting plates protruding from the inner wall of the washing tub 2, the mounting plates being opposite each other and spaced apart, forming the aforementioned slot 51 between the two mounting plates. Alternatively, the mounting component may be a block structure with the slot 51. Mounting component 5 may also be integrally formed with the washing tub 2, or it may be welded to the washing tub 2 or detachably connected.

[0065] It is understood that the mounting component may also take the form of other internal structures, or may take other methods to adjust the installation height of the cap assembly 1 inside the washing tub 2. The present invention does not impose specific limitations on this.

[0066] Example 3

[0067] This embodiment provides a pulsator washing machine, and the pulsator washing machine provided in this embodiment has a basically the same structure as the pulsator washing machine provided in Embodiment 1, with only some structural differences. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0068] In this embodiment, the length of the pressure column 12 in the direction perpendicular to the pressure cover 11 can be adjusted, so that the overall length of the pressure column 12 can be adjusted to suit different loads of laundry. That is, when the load of laundry is relatively large, the overall length of the pressure column 12 can be shortened to increase the space between the pressure cover 111 and the bottom of the washing tub 2; when the load of laundry is relatively small, the overall length of the pressure column 12 can be lengthened to reduce the space between the pressure cover 111 and the bottom of the washing tub 2, thereby increasing the effect on the laundry.

[0069] In this embodiment, the pressure column 12 includes a first part, a second part, and a locking member that are slidably sleeved. One end of the first part is connected to the pressure cover 11. The second part can slide relative to the first part in a direction perpendicular to the pressure cover 11, and the end of the second part away from the pressure cover is closed. The locking member is used to lock the relative position of the first part and the second part after the sliding adjustment of the first part and the second part is completed.

[0070] In this embodiment, the first part is fitted over the outside of the second part, and a lifting rib is protruding from the outer wall of the first part. That is, the first part is a cylindrical structure with an open end, and the second part is a cylindrical structure or a solid columnar structure with one open end and one closed end. In other embodiments, the second part may also be fitted over the outside of the first part, and a lifting rib may protrude from the outer wall of the second part.

[0071] Preferably, the second part is provided with a plurality of threaded holes spaced apart along its axial direction, and the first part is provided with a through hole, which is a circular through hole or a long through hole. The locking element is a screw. By selectively aligning the through hole with one of the threaded holes and inserting the screw into the aligned through hole and threaded hole, the first part and the second part can be locked at different positions.

[0072] It is understood that the locking mechanism can adopt other existing structures, and this embodiment does not impose specific limitations on it.

[0073] In this embodiment, the mounting height of the capping assembly 1 on the washing tub 2 can be fixed or adjustable.

[0074] Example 4

[0075] This embodiment provides a pulsator washing machine, and the pulsator washing machine provided in this embodiment has a basically the same structure as the pulsator washing machine provided in Embodiment 1, with only some structural differences. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0076] In this embodiment, the pulsator washing machine also includes an elastic element, which is located above the pressure cover 11, with its lower end connected to the pressure cover 11 and its upper end fixed relative to the washing tub 2. When there are no clothes in the washing tub 2, the elastic element is in an extended state, and the pressure cover assembly 1 is in a first height position; when there are clothes in the washing tub 2, the elastic element is in a compressed state, and the pressure cover assembly 1 is in a second height position, which is higher than the first height position.

[0077] The elastic element ensures that a certain pressure is applied to the clothes throughout the washing process, allowing the pressure cap 11 to move upward under the pushing action of the clothes and water flow, and downward under the elastic restoring force of the elastic element. This better enables the pressure cap 11 to slide up and down during the washing process, improving the downward pressure on the clothes and enhancing the washing effect.

[0078] Example 5

[0079] This embodiment provides a pulsator washing machine, and the pulsator washing machine provided in this embodiment has a basically the same structure as the pulsator washing machine provided in embodiment four, with only some structural differences. This embodiment will not describe the structure that is the same as that in embodiment four.

[0080] In this embodiment, the upper end of the elastic element is connected to a fixing seat, the fixing seat is detachably connected to the inner wall of the washing tub 2, and the height position of the fixing seat on the inner wall of the washing tub 2 can be adjusted.

[0081] This setting allows for adjustment of the mounting height of the fixing seat according to the amount of laundry and water, thereby adjusting the initial distance between the pressure cap assembly 1 and the bottom of the washing tub 2. This prevents the elastic element from being compressed too much when too much laundry is being washed, which would cause the pressure cap assembly 1 to apply excessive pressure to the clothes and affect the tumbling of the clothes inside the washing tub 2.

[0082] The connection method between the fixing seat and the inner wall of the washing tub 2 can be a threaded connection or a snap-fit ​​connection to the guide rib.
